16. Velorex
They built the Velorex Oskar in Czechoslovakia, in the 50s. And it was one of the strangest cars they ever produced behind the Iron Curtain. And since a motorcycle company built it, it looked more like a three-wheeled bike than a proper car.
It was powered by a 300 cc motorcycle engine with six HP. However, since the car was extremely light, this tiny motor produced a serious performance, as well. Interestingly, the Velorex didn’t have body panels, but had canvas that stretched over the frame rails.
